Thank you changabula for pointing out the great contributions of black Americans. Just another reason why America is so great. You should have also mentioned hip-hop, which is extremely popular all over the world.

Multiculturalism is awesome.

I am doing this to help redress the balance.
I am going to post some information about a few black inventors that managed to get the credit despite facing many obstacles.

Andrew Beard
(1849-1921)
(a farmer, carpenter, blacksmith, a railroad worker, a businessman and finally an inventor)

Andrew Jackson Beard hailed from Eastlake, Alabama, a small town outside of Birmingham. With the emergence of the railroad industry and its rapid expansion throughout the country, an alarming number of railmen suffered serious injuries to their arms and legs when they were crushed during manual style coupling of railroad cars. During manual coupling, a worker would have to attempt to precisely time the moment when two railroad cars being pushed together would be close enough for that worker to drop a metal pin between their connectors, thus engaging the cars. If the worker was off by one second he might severe damage his arm or leg - many in fact had to undergo amputation.

On November 27, 1897 Beard received a patent for a device he called the Jenny Coupler. The Jenny Coupler automatically joined cars by simply allowing them to bump into each other, or as Beard described it the "horizontal jaws engage each other to connect the cars." Beard sold the rights to his invention for $50,000.00 and the railroad industry was revolutionized.

During his lifetime, Beard received a number of other patents, including a steam driven rotary engine, and a double plow.

Miriam E. Benjamin
(second black woman to receive a patent for an invention she called a Gong and Signal Chair for Hotels)

Miriam E. Benjamin was a school teacher living in Washington D.C. In 1888, Ms. Benjamin received a patent for an invention she called a Gong and Signal Chair for Hotels. Her chair, as she stated in her patent application would "reduce the expenses of hotels by decreasing the number of waiters and attendants, to add to the convenience and comfort of guests and to obviate the necessity of hand clapping or calling aloud to obtain the services of pages."

The system worked by pressing a small button on the back of a chair which would relay a signal to a waiting attendant. At the same time a light would illuminate on the chair allowing the attendant to see which guest was in need of assistance. The system was adopted and installed within the United States House of Representatives and was the predecessor of the methods used today on airplanes to signal stewardesses.

Ms. Benjamin was the second Black woman to receive a patent.

Henry Blair

Henry Blair was the second Black inventor issued a patent by the United States Patent Office. His first invention was a seed planter which enabled farmers to plant more corn utilizing less labor in a smaller period of time. Two years later, in 1836, Blair received a second patent for a corn harvester. Blair had been a successful farmer for years and developed the inventions as a means of increasing efficiency in farming.

It is noteworthy that in both of his patents he was listed as a "colored man", the only example of an inventor's race being listed or acknowledged on an issued patent.

Sarah Boone

Sarah Boone received a patent on April 26, 1892 for a device which would help to neatly iron clothing. This device, the predecessor to our modern ironing board was made of a narrow wooden board, with collapsible legs and a padded cover and was specifically designed for the fitted clothing worn during that time period.

Prior to her inventions, people were forced to resort to simply using a table or being creative in laying a plank of wood across two chairs or small tables.

Otis F. Boykin
(invented the electronic control devices for guided missiles, IBM computers, and the pacemaker.)

Otis F. Boykin was born on August 29, 1920 in Dallas, Texas. After graduating high school, he attended Fisk College in Nashville, Tennessee. He graduated in 1941 and took a job as a laboratory assistant with the Majestic Radio and TV Corporation in Chicago, Illinois. He undertook various tasks but excelled at testing automatic aircraft controls, ultimately serving as a supervisor. Three years laster he left Majestic and took a position as a research engineer with the P.J. Nilsen Reseach Laboratories. Soon thereafter, he decided to try to develop a business of his own a founded Boykin-Fruth, Incorporated. At the same time, he decided to continue his education, pursuing graduate studies at the Illinois Institute of Technology in Chicago, Illinois. He attended classes in 1946 and 1947 but was forced to drop out because he lacked the funds to pay the next year's tuition.

Despite this setback, Boykin realized that a Masters Degree was not a pre-requisite for inventive competence. He set out to work on project that he had contemplated while in school. At the time, the field of electronics was very popular among the science community and Boykin took a special interest in working with resistors. A resistor is an electronic component that slows the flow of an electrical current. This is necessary to prevent too much electricity from passing through a component than is necessary or even safe. Boykin sought and received a patent for a wire precision resistor on June 16, 1959. This resistor allowed for a specific amounts of current to flow through for a specific purpose and would be used in radios and televisions. Two years later, he created another resistor that could be manufactured very inexpensively. It was a breakthrough device as it could withstand extreme changes in temperature and tolerate and withstand various levels of pressure and physical trauma without impairing its effectiveness. The chip was cheaper and more reliable than others on the market. Not surprisingly, it was in great demand as he received orders from consumer electronics manufacturers, the United States military and electronics behemoth IBM.

In 1964, Boykin moved to Paris, creating electronic innovations for a new market of customers. Most of these creations involved electrical resistance components (including small component thick-film resistors used in computers and variable resistors used in guided missile systems) but he also created other important products including a chemical air filter and a burglarproof cash register. His most famous invention, however, was a control unit for the pacemaker, which used electrical impulses to stimulate the heart and create a steady heartbeat. In a tragic irony, Boykin died in 1982 as a result of heart failure.

Otis Boykin proved that the setback of having to drop out of school was not enough to deter him from his dream of becoming an inventor and having a long-lasting effect on the world
